BAG-FASTENER.

Original application filed October 20, 1906, Serial 110,339,747.

Specification of Letters Patent.

Serial No. 359,203.

The object of our invention is to construct a fastener for use uponbags, pocket-books and other similar devices, the same comprisingpreferably, a chambered base having a portion of its front wall recessedor cut-out and provided with a catch member having one limb lying insaid recessed or cut-out portion of the base and flush with its frontwall, the other limb extending into said base and a spring designed tobear upon said catch member to hold it in normal position, therebyproducing a fastener which presents a neat appearance with no sharpexternal projecting members liable to become inoperative throughshipment or careless manipulation.

In carrying out our invention, we make use of the structures illustratedin the accompanying drawings, in which Figure lis a front elevation ofour invention. Fig. 2 is a top plan view of the'same. Fig. 3 is a bottomplan View. Fig. 4 is a central vertical section. Fig: 5 is a verticalsection taken on the line ac w of Fig. 1. Fig. 6 is a plan view of theactuating spring, and Fig. 7 is a side view of the actuating springlock.

Similar letters of reference refer to like parts throughout thespecification and drawmgs.

This application is a division of our application for improvements inlocks, filed October 20, 1906, Serial Number 339,747.

I11 the structure illustrated, we make use of but three separate parts,namely, the chambered base i, the spring Z and the combined top pieceand catch member Zc. The chambered base i is rigidly secured to one ofthe bag frame members by the rivets c as shown. The front portion of thechambered top piece it has its front wall extending downwardly and weprovide the same with the inturned flange m which extends into the cutaway portion of the base i as shown in Fig. 4, said inturned flangebeing provided with extensions m to prevent separation of the parts whenassembled, and form convenient stops which will limit the tiltingmovement of the combined top piece and catch member is. Under somecircumstances, however, we may omit these extensions m entirely so as toleave the flange m of the same length as the opening in the base piecei. \Vith the top piece is in position upon the base i, it will be notedthat a rectangular space is left between the flange m andthe top wall 11of the base i, and into this space we insert the spring Z with itscambered central portion. bearing on the top wall 2' and the springtongues Z bearing upon the forward portion of the flange m. In thismanner, any tendency to tilt backward the top piece 70 by pres sure uponits forward side, will be resisted by the inwardly directed springtongues Z bearing upon the inturned flange m.

In order to prevent accidental dis lacement of the top piece Zc, in casewe (lb not use the extensions m upon the flange m, We may make use ofthe projections 7c upon the extreme end walls of the top piece k, suchprojections extending through apertures 0 in the top wall of the base i.WVe may, however, use both the extensions m and the projections 7c, butwe do not desire to limit ourselves to the use of both of such parts inconjunction, as either method will secure the top piece 7c againstaccidental displacement. Where We use the extensions Zc upon the ends ofthe top piece ]c, we provide the forward edge of the same with a notchwhich upon tilting back the top piece is around the upper rear edge 1"of the base as a fulcrum, is re- ?isted by the pressure of the springtongues will come in contact with the forward end of the aperture 0 andthus limit the extent to which the top piece 70 can be depressedrearwardly as indicated by the arrow in Fig. 4. We provide the forwardportion of the flange m with the indentations p to receive correspondingprojections upon the bag frame member I).

The springs illustrated in Figs. 6 and 7 are formed from a single flatpiece of metal, centrally cambered as illustrated and having the Asshown in Figs. 4 and 5, said notch k spring. tongues Z formed by cuttingaway from points remote from the ends of the piece of metal towards theends as illustrated in Fig. 6, with such tongues upwardly bent in theOpposite direction from the camber of the metal. Under ordinarycircumstances and in the locks shown, the metal between the tongues Z asillustrated may be cut away. There are, however, certain conditionswhere pressure [brought to bear u on the spring tongues l of thestructure ilus trate in Figs. 6 and 7, might tend to tilt the bearingpoints of the spring In this shall. be in substantial alinement.

manner, all tendency to tilt under. pressure brought to bear upon thetongues land the central cambered portion Z will be com- I pletelyovercome.

\ It'will thus be seen that we have provided aloek-in which we havereduced the actual number of parts to three, and that whenas- ,sembled,and in brother device, tlie lock presents a neatand osition upon abagframe tasty appearance. with no sharp external projections and with theoperating parts so I protected as to leave practically no liability fordisplacement without breakage. The partsare ofsuch a shape as to lendthem selves readily .to manufacture by the use .of

suitable punchesand dies from ordinary shee m l- .We claim: I 1. ,In abag fastener, the combination of a chambered base havinga portion ,ofits front 40 Inpon t e top of said base, said top piece having a portionandto walls cuteaway, ia top piece resting ,of its front ,wall,extending downwardly into said cut-away portionjof ithebase, a flange atthe lower end of saidextended portion, said flange extending into sacham ere ba n a p i g y g b tween and bearmg upon said flange and thetop wall of said base.

2. In a fastener for bag frames, the combination of a bag frame member,a chambered base secured to said frame member, a com bined top piece andcatch member comprismg a top piece resting upon said base and anL-shaped catch member integral with and extending downwardly from thefront wall of. said; top piece and intosaid chambered base, and a springlying between and bearing upon the inwardly extending limb of said catchmember and the top wall of said base.

.3. In a bag fastener, the combinationof a chambered .basehaving aportion of its front wall cut-.out,a chambered top piecehaving a portionof its frontwall extending. downwardly into the gut-out portionofsaidbase,

, a flange. at thelower end of said downwardly extending ortion, saidflange extending into Said cham ered base, a spring bearing upon saidflangeand. stops upon. said chambered top piece to limit its tiltingmovement against the tensionof. said spring.

4. In a fastener for bag frames, the combination ofa chambered basehavinga portion of its front wall cut away, with a catch membercomprisinga to piece resting upon thetop of. said base, an having aortion of its front side extended ,downjward y. into said cutawayportion, of; the base and lying flush with; the front wall thereof,,aninwardly extending flange at the lower. edge of said downwardlyextending portion, a spring within the base bearing upon said flangeand,

stops upon the endsof said, catch, member and projecting throughapertures in, the top ofsaid base to limit, its .movementagainst thepressure of said spring.
